Filed July 28, 1932 Patented Dec. 19, 1933 UNITED STATES PATENT OFFICE I VISE John R'. Long, Los Angeles, Calif. Application July 28, 1932. Serial No. 628,501

2 Claims. (01. 81-41) My invention relates to an improved vise for use on work benches or other supports, the primary object being to provide a base and improved means by which the vise can be selectively arranged in a multiplicity of positions and easily secured therein by the operator, whereby the vise is adapted to serve the user more efficiently and effectively and the user is .enabled to perform more work with greater accuracy than heretofore. A further object is to provide improved means such as a screw and cooperatingparts which will when turned tighten the jaws of the vise and lock the vise against rotation simultaneously or vice versa, when reversed open the jaws and free the vise for rotation, simultaneously. Thus a single operation of the screw performs two functions. Among further objects are simplicity coupled with rigidity of construction and inexpensiveness.

In the accompanying drawing forming part of this specification, Fig. 1 is a side elevation of my invention, a portion being broken away and in section to expose a detail of construction; Fig. 2 is a front elevation, and Fig. 3 is a side elevation of a portion of the base.

My improved vise may be of any suitable design, that shown being one of many possible variations. In this structure an essential part of the vise is a main body A having a comparatively stationary jaw 10, a longitudinal guide shank 11, and a jaw adjusting and tightening screw 12 disposed longitudinally along a side of said shank, swiveled at 13 on one end and to said shank and provided with the handle 14 on its other end by which it is revolved in said body. Another essential part of the vise is the movable body'B which has a passage 15 throughwhich the shank extends, a threaded bore 16 in which screw 12 is threaded and engages, and a movable jaw 17 which coacts with the stationary jaw 10 to engage and hold work. As the screw is revolved by handle 14 the jaws 10 and 17 are opened or closed to tightly engage and hold any work desired, the movable jaw body B being bodily moved along shank 11 by screw 12. the movable jaw member is carried by the stationary jaw member at all times.

For the purpose of variably supporting the base so that it can be supported at different angles and various positions for the convenience of the operator, a base C having flanges 20 is adapted to be mounted upon a bench or other support D by bolts 21 or other suitable means passing through said flanges and into said support. This base extends beyond the bench and Thus said extension is passaged vertically at 22' and horizontally at 23 to receive said socketa swivel pivot 24 either in vertical upstanding position asshown in Fig. 1 or in horizontal outstanding position as shown in Fig. 3, in either of which positions the pivot is locked securely by the removable tapered pin or key 25. The passages 22 and 23 intersect and the key traverses at said intersection.

To register and engage with the pivot 24 in either of its selected positions the body A of the vise is provided with a plurality of intersecting pivot receiving passages 26 and 27, the former being vertical upwardly into the base and the latter horizontal across the vise. This double passaging of the body and selective positioning of the swivel pivot provides a multiplicity of positions in which the vise can be adjusted upon the base C. For instance when it is desired to use the vise in upright position as shown in Fig. 1, the pivot is secured by tapered key 25 in upstanding position in the base C and the main body of the vise is swiveled with the pivot entering the vertical passage 26. In this condition the vise can be swung in a horizontal plane on the base into any horizontal direction desired, thus facilitating the user. Or if desired the vise can be turned on either side and the pivot placed upwardly in the passage 27, which previously was horizontal, in which position thevise can be turned into any selected direction desired to facilitate the operator. Also when desired the pivot can be secured in the base by its key in either horizontal (see Fig. 3) or vertical position and the vise adjusted with either passage 26 or 27 over the pivot so that the vise can be turned in substantially any direction.

In any of these selected positions the vise can be clamped and held stationary against rotation and removal from the pivot by the provision of a slot E in its body which enters the vertical pivot receiving passages 26 and 27 and intersects screw 12. This slot enters both passages 26 and 27 being so arranged that when the screw 12 is tightened by turning handle 14, said screw first causes the jaws l0 and 17 to clamp the work and further tightening causes the passages 26 and 27 to contract against spring tendency and tighten their walls upon the pivot 24, thus automatically causing the main body to hold the vise in selected stationary position on its pivot. Elasticity of the main body causes the body to release from grasping the pivot when the screw is loosened, thus permitting the main body to turn or be removed. Thus a single operation of the Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A vise, comprising, a main body having a stationary jaw, a rearwardly extending guide shank and a plurality of intersecting pivot re.-

ceiving passages extending vertically and horizontally, an operating screw swiveled in said body and extending rearwardly along side of said shank, a movable body slidably engaging said shank having a threaded bore adapted to receive said screw and a jaw adapted to movably coact.

with said stationary jaw, and a base having a pivotadapted to swivel in either of said pivot receiving passages, whereby the main body is free to swing thereon while at different angles, said main body having a downwardly extending slot across said screw and entering both of said pivot receiving passages whereby when the screw is turned and the jaws tightened the walls of said pivot receiving passages are contracted and the main body clamped rigidly upon said pivot.

2. A vise, comprismg, a main body having a stationary jaw, a rearwardly extending guide shank and vertical and transverse pivot receiving passages, an operating screw swiveled in said body and extending along a side of said shank, a movable body slidably engaging said shank having a substantially horizontal threaded bore adapted to receive said screw and a jaw adapted to movably coact with said stationary jaw, a base having a plurality of pivot receiving sockets extending in different directions, a pivot adapted to be removably held in any of said sockets whereby the main body is free to swing thereon, and a key holding said pivot in its socket, said main body having a downwardly extending slot across said screw and entering said pivot receiving passages whereby when the screw is turned and the jaws tightened the walls of said pivot receiving passage are contracted and the main body clamped rigidly upon said pivot.
